another valve/spring question..

[vandancouver]

this is proabably stupid of me to ask. the valve spring piece..the circle with the figure 8..does that go on the actual valve about a 1/4inch up where its wider..or does it fit over the bottom piece..the piece the valve touches when it comes down? cause when i re did it i put it on the actual valve..

 

[jr dragster T]

The spring retainer should sit in the groove like you where saying about 1/4" from the end. It should pull the valve into the seat.

 

[vandancouver]

that means the spring is held up about a 1/4 inch from the bottom?

 

[jr dragster T]

Yes.

 

[vandancouver]

well wtf why wont it work? it ran purrfect before. now it wont even start. think the cam key isnt lined up properly? what else could it be..its not like i took it apart and shook it and dropped it..

 

[jr dragster T]

Its not the cam key your worried about. Its more lining up the dimples on the cam/crank.

 

[vandancouver]

so how do i do that? i need to drain the oil, take the crankcase off..then what? set the valve clearances or what? i guess im not sure and i appreciate the help.. so what do i do when i have the crankcase off

if you have dots, align them to each other

 

[vandancouver]

the dots are where? i see them in the crankcase by the camshaft or what? please explain mike, your the go kart guru!

 

[mike75925]

on the edge of the gears, if it has them they will be there. some like motos have lines. if dots, they will be the only ones present, usually one between two teeth on one piece and one directly on a tooth on the other.

please explain mike, your the go kart guru!

Ohh so hes the only guru around here?

This is what it should look like properly timed in. The crankshaft has a dimple and the cam has a dimple. I've placed a chaulk dot on the crank dimple to be more clear. The cam will only go in at TDC and the dimples should line up.

you aren't by chance getting jealous are you tyler? he hasn't experienced your knowledge yet.

 

[jr dragster T]

Well I guess you could say jelous. But once hes here for a while he will know theres alot of good helpers around here. Its all good.

thanks dragster tyler for the picture of the dots. i would go check it out right now but my wife needs me to help her at our store (we own a small clothing store) i need to mount some things..she comes first right now. but the instant im done im going to the go kart!

tyler- i see the white chalk dot you put on there..but whats there if you wiped the chalk off, just a regular small dot? i mean, its obvious when i look at it?

 

[jr dragster T]

Yes, the dot on the crank should be pretty obvious.

 

[vandancouver]

it works now. thanks
